Central European Time (Berlin)

Germany uses Central European Time (CET/CEST) and has been a key player in European timezone standardization. Germany adopted standard time relatively early in 1893, following the expansion of the railway network which demanded uniform timekeeping. Berlin is the capital and cultural heart of Germany, while Frankfurt is the financial center, home to the European Central Bank and the Frankfurt Stock Exchange (Deutsche Börse). Germany is Europe's largest economy and the world's fourth-largest, making its timezone critically important for global business. The country's manufacturing sector — including automakers BMW, Mercedes-Benz, and Volkswagen — coordinates supply chains across CET. Germany's reunification in 1990 was seamless from a timezone perspective since both East and West Germany used CET, though the two states had different DST rules during the Cold War. Germany's central position in Europe means Berlin time is a natural reference point for continental European business. The country's tech hubs in Berlin, Munich, and Hamburg have made CET increasingly important for the European startup ecosystem.
